CHARLES BAZZILL, or

TRAP

Application filed May 19,

To all whom it may concern:

Be it known that I, CHARLES BAZZILL, ,a citizen of the United States,residing at Trinidad, in the county of Las Animas and State of Colorado,have invented new and useful Improvements in Trap Nests, of which thefollowing is a specification.

This invention relates to devices for use inthe raising of poultry andhas for its object the provision of a novel trap nest which willautomatically disclose which hens are layers and which are useless. Animportant and more specific object is the provision of a trap nestequipped with means for distributing eggs laid by successive hens incertain individual compartments which correspond to elastic identifyingmembers which are engaged u on the neck of the hen as the hen leaves tienest, the co-relation of these marking tags with the egg compartmentsgiving eflicient data as to the layers and non-layers so that the flockmay be weeded out by the removal of the drones.

Another object is theprovision of a device of this character which is ofrotary nature and which is spring operated to bring the successive eggcompartments in a position to receive eggs laid in the discharge chuteso that error in checking up will e almost impossible.

Still another object is the provision of a trap nest which will besimple and inexpensive in manufacture, sanitary, efiicient and durablein service and a general improvement in the art.

\Vith the above and other objects and ad vantages v.in view theinvention consists in the details of construction to be hereinafter morefully described and claimed and illustrated in the accompanyingdrawings, in which:

Figure 1 is a side elevation of the p'lete device,

Figure 2 is a top plan view thereof,

Figure 3 is a bottom plan view,

Figure 4 is a horizontal section on the line 4-4: of Figure 5,

'Figure 5 is a longitudinal section on the line 5-5 of Figure 2,

Figures 6 and 7 are detail views of the latch and its cooperatingelements.

Referring more particularly to the drawings I have shown my device ascomprising an upstanding cylindrical casing 10 open at its bottom andclosed at its top by a conical COID- rein.

roof 11. This casing is supported upon any desired number of legs 12which will hold the bottom somewhat elevated above the ground, floor orother surface. At one point in its periphery the casing 10 is formedwith a door opening 13 normally closed by a pair of doors 14 which arehinged at 15 and which carry curved actuating arms 16 for a purpose tobe described. The opening 17 immediately above and may be considered apart of the opening 13. At the upper corners of the opening 13 are slots13. Connected with the doors 14 near their upper corners are springs 14:which bear against and which are secured to curved plates 14E mountedagainst the inner wall of the casing. These springs pass through theslots or notches 13 and are so arranged as to hold the doors in eitheropen or closed position.

Surrounding and rotatably mounted upon the lower end of the casing is aring like structure 18 including upper and lower members 19 and 20respectively which have the space between them divided by partitions 21into a plurality of compartments 22 designed for the reception of eggs.Carried by the lower ring member 20 and projecting inwardly toward thecenter is a-series of pins 23 with which co-operates a pivoted latch 24-mounted upon a supporting plate 25. The latch is held in normal positionby s )rings 24 The bottom of the casing 10 is normally closed by a plate26 which is hinged at 27 at a point most remote from the door opening13. At a diametrically opposite point this closure plate carries a lugor ear 28 with which is connected one end of a rod 29 which has itsother end pivotally connected with the latch 24 as shown at 30. The

springs 24: hold the bottom plate normally in its uppermost position.The end 31 of the latch acts as a stop, as will be described, and theother end is of book shape to de fine a shoulder 31 The bottom closureplate 26 is provided with a central hole 32 leading into an inclined eggdischarge chute 33 which may preferably be lined with felt or other softpadding which will reduce danger of breaking eggs rolling therealong.The outer end of this chute is designed to discharge eggs intothesuccessive compartments 22. It should be mentioned in passing that therotatable egg compartment member is intended to be placed under tensionby means of a spring 34, which has one end secured to the eggcompartinent member and which has its other end secured to an outwardlyextending bracket 35 carried by the casing, the purpose being that byrotating the egg carrier the spring will be placed under such tensionthatthere is quite a strong tendency for the egg carrier to rotate, suchrotation being permitted whenever the latch 24- is moved out ofengagement with the successive pins 23.

' Rotatably 'mounted upon the top of the casing is a ring 36 preventedfrom downward displacement by lugs 37 thereon engaging against the upperedge of the wall of'the casing. This ring 36 is formedwith openings 38designed'to registersuccessively with the opening 17. The openings 38alternate with solid tongues 39 which are for the purpose of closing theopening 17 whenever such'is desired depending upon the circumstances ofthe particular case. The ring 36 is secured with respect to the carrierby means of an elongated post 40 which has one end secured to thecarrier and which has its other end secured to an ear 41 on the ring 36on the casing. hen the device has been used by a number of henscorresponding tothe number of egg compartments, it is to be noted thatone hinged door will come opposite the post 40 and this post thenoperates to prevent the doors from swinging open.

In order to mark the individual hens subsequent to laying,.I provide anelastic band l2 designed to be engaged about the neck of the fowl andthis band is held upon pins or posts 43 at the corners of the openings38.

In the operation it will be seen that initially the control spring mustbe placed under tension, an act which is easily accomplished by holdingthe casing stationary and rotating the egg carrier to bring the desiredone of the compartments therein in alignment with the discharge chute.The doors are initially open and held so by the springs 1 F, and thearms 16 obstruct the opening. hen a hen steps through the doors 14: andenters the nest, the pressure of her body against the arms 16 causes thedoors to swing shut behind her, and the weight of the hen upon the freeend of the plate 20 causes this plate to swing downwardly. At this timethe resultant downward movement imparted to the rod 29 causes the latch24 to swing upon its pivot, so that the end 31 will be out of the pathof pins 23 while the shoulder 31 moves into their path. This permits therotary memher to turn one step or until the next pin engages the stopshoulder 31. hen an egg is laid it rolls down the discharge chute intoone of the compartments and when the hen subsequently steps out of thenest the bottom plate will return to its normal position the resultbeing that the with the outlet end of the egg chute.

.There are two pins for each egg compartment. When leaving the nest thehen will naturally pass her head through the small opening 17 exposed atthe top of the door opening and will then, according to instinct pressoutwardly on the doors which will result in swinging them to openposition, the springs 14? then holding them open.

36 and that they are disposed about the sue cessive openings or cut awayportions 38. When the hen places her head through the opening andpresses outwardly on the doors the band will be disengaged fromitssupporting pins l3 and will remain on the neck of the fowl. It isintended that these bands be numbered or otherwise marked to distinguishthem one from another and that the various egg compartments becorrespondingly numbered so that the operator or attendant may ascertaindefinitely which are the laying and which are the idle hens in theflock. A

From the foregoing description and a study of the drawings it will beapparent that I have thus provided a simply constructed and consequentlyinexpensive trap nest which will be Very eflicient for the purposespecified and which on account of the few'n'ess of the parts should havea long life.

lVhileI have shown and described the preferred embodiinent of theinvention it is of course to be understood that I reserve the right tomake such changes in the form, construction and arrangement of partsaswill not depart from the spirit of'the invention or the scope ofthesubjoined claims.

Having thus described my invention I claim:

It is to be noted that the elastic bands are carried by the upper rotaryring 1. A trap nest comprising a cylindrical casing having a dooropening and a relatively small opening thereabove, liinged doorsnormally closing the door opening, a rotatable egg compartment carriedby the lower end of the casing, a bottom hingedly mounted witihn thecasing and having an opening, a discharge chute beneatlr the bottomreceding from the opening and designed to discharge eggs into successivecompartments, a ring member rotatably mounted uponthe upper end ofthecasing and formed with cut out portions corresponding to said eggcompartmentsand adapted to register with said relatively small opening,and meansjfor holding a series of elastic bands around saidcut outportions, and means operated by depression of said bottom member forrotating the egg carrier step by step.

2. A trap nest comprising aicylindrical casing having a closed top andan open bottom, said casing being formed with a door opening and arelatively small opening leading thereinto, a pair of hingedly mounteddoors normally closing the door opening, an egg carrier rotatablymounted upon the lower end of the casing and divided into compartments,a bottom plate movably mounted within the casing, a latch device carriedby the casing, an operative con nection between said movable bottom andsaid latch device, spring means tending to rotate the egg carrier in onedirection, a plurality of stops carried by the carrier and co-operatingwith said latch for holding the carrier at a selected position, a ringmounted upon the upper end of the casing and having openings adapted toregister with said small opening, means for holding a series of markingelements around said last named openings, a rotatable egg carrier at thebottom of the casing moving synchronously with said ring.

In testimony whereof I affix my signature.
